Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type for your specific Cavalier engine.
* Wrench(es): You'll likely need a variety of sizes, including those that fit the tensioner pulley bolt(s).
* Socket set: A socket set with extensions and a ratchet will make working in tight spaces easier.
* Jack and jack stands (highly recommended): Safely lifting the car allows for better access.
* Gloves: Protect your hands.
* Shop rags or paper towels: For cleaning.
* Pliers (optional): Might be needed to help maneuver the belt.
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Disconnect the negative battery terminal to prevent electrical shorts. Always prioritize safety.
2. Locate the Tensioner: The serpentine belt tensioner is a pulley with a mechanism to create tension on the belt. On a Cavalier, it's usually located on the passenger side of the engine. It'll have a bolt that needs to be loosened or a lever that needs to be manipulated to release tension.
3. Release Belt Tension: This is the most crucial part. Using the appropriate wrench (often a 13mm or 15mm, but check your manual), loosen the tensioner bolt or lever. You will need to apply pressure or leverage against the tensioner to keep it released while you remove and install the belt. It might help to have a wrench or similar tool to hold the tensioner in the released position while you work with the belt.
4. Remove the Old Belt: Once tension is released, the belt should be loose enough to slip off the pulleys. Start by lifting the belt off the smallest pulley (often the crankshaft pulley). Work your way around, carefully removing it from each pulley.
5. Inspect Pulleys and Belt Routing: Before installing the new belt, carefully examine the pulleys for damage or wear. Note the routing of the old belt—take pictures if needed! Make sure you understand the correct path of the belt around all the pulleys. This is critical. An incorrect routing will damage the belt and components.
6. Install the New Belt: Carefully route the new belt onto the pulleys, following the same path as the old one. It might be easier to start with the largest pulley.
7. Re-tension the Belt: Once the belt is on all the pulleys, carefully release pressure on the tensioner, allowing it to retract and put tension on the belt.
8. Check Belt Tension: Make sure the belt is properly tensioned. You should be able to push on the longest span of the belt between pulleys with your thumb, and it should deflect approximately ½ inch. Consult your manual for precise specifications.
9. Reconnect Battery: Reconnect the negative battery terminal.
10. Test: Start the engine and listen for any squealing or unusual noises. Check the belt again to ensure it's not slipping or rubbing.
Important Considerations:
* Engine Size: The exact procedure might vary slightly depending on the engine size in your 2000 Cavalier (e.g., 2.2L, 2.4L).
* Repair Manual: A repair manual specific to your vehicle is invaluable. It will have diagrams, torque specifications, and detailed instructions.
* Safety: If you're not comfortable working on your car, take it to a qualified mechanic.
This guide provides general steps. Improperly installing the belt can lead to damage to your engine. If you're unsure about any step, seek professional help. Remember to consult your vehicle's repair manual for the most accurate and detailed instructions.
